Six Electrodes
The 6-electrode method with lead II and lead V5 is effective for monitoring myocardial ischemia.
You can improve monitoring accuracy considerably by adding lead V4 to this combination. Va
and Vb can be at any position of the standard 12 leads V1 to V6, but V4 and V5 are most
appropriate for myocardial ischemic monitoring.
